我公司在引进联邦德国先进技术的同时,也引进了大批汽车装配工具——扭力扳手。由于我国至今没有扭力扳手计量检定规程,所以给扭力扳手的检测带来了无法可依的局面。我们认为,目前可参照国际标准ISO 6789进行检测。ISO 6789中规定: 扭力扳手最大扭矩值的偏差为±4％。扭力扳手最大扭矩值20％处偏差为±7％。扭力扳手被测值允许偏差和偏差值基本计 While introducing the advanced technology of the Federal Republic of Germany, our company also introduced a large number of car assembly tools - torque wrenches. Since our country has no torsion wrench measurement verification procedures, so the detection of torque wrenches brought inconceivable situation. In our opinion, we can now test with reference to the international standard ISO 6789. ISO 6789 provides: torque wrench maximum torque deviation of ± 4%. Torque wrench maximum torque value of 20% at a deviation of ± 7%. Torque wrench measured value of the allowable deviation and deviation of the basic gauge
